問題5

The customer router connects to the operator's network through the S1/0 interface. The S1/0 interface uses the default configuration.
The following route is configured on the router: [MSR]ip route-static 0.0.0.0 0.0.0.0 Serial1/0
However, when viewing the routing table through display ip routing-table, it is found that the route is not displayed in the routing table. Based on this, it is speculated that the possible reason is ______. (Multiple choice)

A. S1/0 interface is shutdown

B. The configuration is wrong, the next hop of the route should enter the IP address of the opposite end instead of the interface name S1/0

C. S1/0 interface has no IP address

D. The configuration is wrong, you should exit to the system view to configure the route to take effect

正確答案: A,C

問題6

The customer's network connection is shown in the figure.

Among them, the IP addresses of RTA, RTB, and RTC are respectively 2.2.2.1/24, 2.2.2.2/24, 2.2.2.3/24. To realize the intercommunication between RTA, RTB and RTC, configure the following frame relay MAP on RTA correct ?

A. fr map ip 2.2.2.1 40 60

B. fr map ip 2.2.2.1 40

C. fr map ip 2.2.2.2 40

D. fr map ip 2.2.2.3 50

正確答案: C,D

問題7

Two MSR routers are directly connected back-to-back through Serial1/0, and one of the MSR routers sees the following configuration: ★
interface Serial1/0
ip address 8.8.8.2 255.255.255.0
#
interface GigabitEthernet0/0
port link-mode route
ip address 100.1.1.2 255.255.255.0
#r
ip 1
version 2
network 0.0.0.0
#
ip route-static 0.0.0.0 0.0.0.0 8.8.8.1
Assuming that both routers are correctly configured with RIP and all interfaces are UP, which of the following analyses are correct about this configuration?

A. The neighboring router at the opposite end cannot learn the default route generated by RIP from this router

B. A RIP default route will be sent from the outgoing interface Serial1/0 to the peer neighbor

C. The opposite neighbor router can only receive one RIP route

D. RIP routing update packets can only be sent or received from the Serial1/0 interface of the router

正確答案: A,C

問題8

The two routers MSR-1 and MSR-2 are interconnected through the S0/0 interface, and the two routers learn the routes of the LAN segment by running the RIP protocol.
See the following configuration commands on MSR-1:

問題10

The two empty-configured MSR routers are connected as shown in the figure. By configuring the IP address, the GE0/0 interfaces of the two routers can communicate with each other.

Now the following configurations are added to the two routers respectively:
RTA:
[RTA]ospf
[RTA-ospf-1]area 0
[RTA-ospf-1-area-0.0.0.0]network 192.168.1.1 0.0.0.3
[RTA-GigabitEthernet0/0]ospf dr-priority 2
RTB:
[RTB]ospf [RTB-ospf-1]area 0
[RTB-ospf-1-area-0.0.0.0]network 192.168.1.1 0.0.0.3
[RTB-GigabitEthernet0/0]ospf dr-priority
Then after the OSPF neighbor status is stable, ______.

A. Of the two routers, one is DR and the other is DRother

B. OSPF interfaces have the same priority, and no OSPF DR election is performed on the 192.168.1.0/30 network segment

C. Of the two routers, one is DR and the other is BDR

D. The neighbor status of the two routers are FULL and 2-Way respectively

正確答案: C
